THE GYM FOR TWO OF THOSE INCIDENTS. HE'S CURRENTLY SUSPENDED FROM HIS JOB AS PRINCIPAL. A LOCAL WAR VETERAN ACCUSED IN A DEADLY ROAD RAGE ATTACK. THE PROSECUTION INTRODUCED NEW EVIDENCE FROM THAT DAY AND FATHER OF FIVE WAS KILLED IN A GROCERY STORE PARKING LOT. SHANNON PERRINE HAS BEEN IN THE COURTROOM. YOU'RE LIVE FROM WASHINGTON COUNTY. WHAT HAPPENED TODAY? Reporter: WE CAN TELL YOU, THIS ALL STARTED WITH A ROAD RAGE INCIDENT AND IT ENDED WHEN BRANDON THOMAS SHOT AND KILLED VAUGHN SEMINELE. THE DEFENSE IS ARGUING THE NEW CASTLE DOCTRINE PROTECTS THOMAS SAYING THE PERSON HAS A RIGHT TO DEFEND HIMSELF ON HIS OWN PROPERTY, IN THIS CASE HIS VEHICLE. THE D.A. SHOWED A PICTURE OF HIM HIGH PRESSURE HE ARGUED THERE'S NO MARKS ON HIS FACE INDICATING HE WAS PUNCHED. THE PROSECUTION SAYS IT'S UNCLEAR WHETHER HE FIRED HIS GUN FROM INSIDE OR OUTSIDE HIS HUMMER BACK IN OCTOBER 2012. A FORENSIC SCIENTIST TESTIFIED IT DOESN'T PROVE WHERE HE WAS WHEN HE PULLED THE GUN TWICE. THE PROSECUTOR ALSO TRIED TO SHOW HE'S A DRUG USER. A BLOOD TEST REVEALED LOW LEVELS OF MORPHINE. A NARCOTICS OFFICER TESTIFIED THAT HEROIN USERS OFTEN SCRAPE OR LICK THE STAMP BAG TO GET EVERY LAST TRACE OF THE DRUG. THOMAS'S FELLOW SOLDIER AND FRIENDS HAVE SAID HE'S NOT A VIOLENT PERSON. EVEN BEEN IN THE MILITARY HAVING TRAINING IN THESE TYPES OF SITUATIONS, ANY NORMAL CIVILIAN WHO IS BEING THREATENED AND ATTACKED WOULD HAVE DONE THE SAME THING, IN MY OPINION.
